Biometric authentication belongs to the areas of cybercrime and cybersecurity, digital society and digital transformation. It is a modern method of securely protecting digital access or devices. Unique physical characteristics of a person, such as a fingerprint, facial recognition or iris scan, are used to confirm a person's identity.
In contrast to traditional passwords or PINs, biometric authentication involves using something that only the respective user possesses - their body. This makes it much more difficult for hackers to gain access, as biometric data cannot simply be guessed or copied.
An everyday example: many people unlock their smartphone using fingerprint or facial recognition. The mobile phone checks whether the finger or face matches the stored user and only then grants access to the device. Thanks to this technology, digital identities and sensitive data are better protected against theft or misuse. At the same time, biometric authentication simplifies access to digital applications, as passwords no longer need to be memorised or entered.
